CHANGE-SPEED GEARING.

Patented June 9, 1.914.

Application tiled August 11,f1912. Serial No. 715,127.

T0 all whom it may concern: 1, Be it known that we, FRED W.l SPAGKE, DALMA'R T. BROWNLEE, and WILLIAM SPAGKE, citizens of the United States, 'residing at Indianapolis, in the county of Marion and State: of Indiana, havev invented a new anduseful Change-Speed Gearing, of which the following is a specification.

41t is the object of our invention to provide a combination clutch and variable speed gearing wherein the clutch and the gears are controlled in common. Our improved clutch andgearing is particularly designed for use' between the motor and driving wheel pli a motor cycle"or"light parcel delivery ve- 'c1e.

The various novel features of our invention will appear from the description" and drawing and will be particularly pointed out inthe claims.

The single gitudinal section through a gearing embody- .ing our invention.

The casing 10 fis preferably made of two parts, bolted together. A central shaftll is mounted in this casing in ball bearings 12 and 13. Two gears 14 and 15, of different sizes, are rotatably mounted on the shaft 11 and mesh with gears 16 and 17, respectively, fixed on a .counter-shaft 18. This counterpin 19 extending between the two halves of the casing 10. The gear 14 is integral with or otherwise fixed in relation to a sleeve 21, on the shaft 11,

on which sleeve a sprocket wheel or other power-transmitting device 22 is fixed and a larger sprocket wheel or other power-transf :mitting device 23 is rotatably mounted. The

sprocket wheel 23 is connected to' the motor or other' source of power, and the` sprocket wheel 22 to/the driving Wheel'of a motor cycle or otherv driven mechanism; or vice versa. The sprocket wheel 23 is formed on the exterior of a casing 24 having a removable cover 25. The inside of the' casing 24 is provided with inwardly extendingteeth 26',- similar to gear teeth, which engagein notches in the peripheries -of clutch disks 27 and 28. Alternating with the disks 27 and 28 and the casing 24 are the cooperating clutch disks 29, the inner edges of which are notched to receive/:teeth 31 on the periphery of a spider 32- fixed on the end of the shaft figure of the drawing is a lon# .face cna pin 11.` The disks 27, 28, and 29 are spaced apart by woven asbestos 33 or other siiitable clutch facing, and are movabletoward and from the casing 24. along the teeth 26 and 31.y The disk 28 extends inwardly, being fastened at its center to one end of a rod 34 freely mounted in a longitudinal o ening in the sha-ft 11, and is pressed towar the casing 24 by a compression spring 35 mounted between it and the cover 25; the disk 28 and cover 25 may be shaped to forma pocket for the spring. If desired, the plate 28 may have a lsliding bearing on a shoulder 36 4 formed on-the spider 32. Then the s ring 35 is expanded, it `clamps the disks 2 28, and 29, the casing 24, and the asbestos 33 all rmly together, so that the spider V32 and shaft 11 rotate with the wheel' 23. 'The endA of the rod 34 which projects into the open-- ing in the shaft 11 bears against one end of, or may be integral with, an alined rod 37, also located in such opening. The other end of the rod37 is cut off obliquely,'and cooperates with a correspondingly oblique sur- 38 which is'slidable in a trans-- verse opening in the shaft 11. The pr0jecting end of the pin 38 is wedge shaped, and coperates with a pointedplug 39 set in the inner face of a gear shifter ring 40 movable along a spline on the shaft 11. The plug 39 and pin 38 coperate as double acting cams. When the ring 0 is in its central position, as shown, itpus esthe'rod 34land disk28 to the left to compress the spring 35 and relieve ythepressure on the clutch plates 27 28, and 29, thus releasing lthe clutch. When the ring 4() ismoved either way from its central position, it allows the pin 38 to slide transversely and the rods 37 and 34 to slide longitudinally 4of the shaft, ,sov that the spring 35 may lock the clutch.

The ring 4() is provided on its opposite faces with teeth 41 and42, which engage corresponding te'eth 43 and 44 on the gears 14 and 15 when said ring is moved toward said two gears respectivel grooved in its periphery to receive a shifter -fork 45, the `head 46 'of which is in screw engagement with `a shifter screw 47 operable by the operating lever 48. When the lever 48 is moved in one direction or the other from its central position, it Jthrows in bot the proper gears and the clutch, releasm tatabl vgears on said countershaft both when it is returned to its middle position. If the movement is such that the teeth 4l and 43 are thrown. into engagement, power v is transmitetd from the lsprocket wheel 28 through the clutch, the spider 32 40, the gear let, and

the shaft l1, the ring the sleeve 2l to the sprocket wheel 22,y which parts all rotate in unison. If the movement of the lever 48-is such that the teeth 42 and 44 are thrown into engagement, power is transmitted from the vsprocket wheel 23 .through the clutch, the spider 32, the shaft l1, the gear i5, the gear ,17, the countershaft 18, the gear 1 6, the gear le, and the sleeve 21 to the sprocket wheel 22, which now operates at a lower speed than does the sprocket wheel 23.
